I, for one, like steering column dimmer levers. I can recall frantically stamping on the floor with my foot to find the dimmer switch. With the steering column lever it is easier to flash an oncoming driver to dim his/her lights. The industry should standardize on dim and bright positions with the lever. I like forward bright and backward dim; seems logical. Possibly the car design people offering inconsistent positions for steering column lever to get dim and bright is a source of dissatisfaction with the steering column control.
It would be good if rear seat foot and legroom was brought back to what cars had in the 1930s to somewhere in the 1950s. Some cars now are impossibly crowded in the back seat when the driver has the room what he/she wants. I do not have a firm date on when rear seat foot and legroom was reduced to a minimal amount but it seemed to have gone away when no one was looking. In the 1930s to the 1950s even low price cars had good rear seat foot and legroom.
Yes, wing windows were good to have. I would pay a good amount of money (200 dollars?) to get them as an option for a new car. They were effective at keeping front seat passengers cool in hot weather in some parts of the country but not all.
